역추적 기술은 해킹이 발생했을 때 해커의 실제적인 위치를 추적하는 기술이다. 해커의 위치를 추적하기 위해 현재 가장 널리 사용되는 방법은 시스템 관리자의 시스템 로그 분석과 시스템 관리자 사이의 상호 정보 교환을 통한 수동적인 역추적 방법이다. 그러나 수동적인 역추적 방법은 수작업으로 수행되는 시스템 로그 분석과 관리자의 개입으로 인하여 땀은 비용이 요구되고 추적 시간의 지연이 발생하기 때문에 이러한 수동적인 방법으로는 해커의 위치를 실시간으로 추적할 수 없다. 만약, 네트워크의 특정 패킷을 식별 가능한 형태로 가공할 수 있다면, 특정 패킷의 이동 경로를 효과적으로 추적할 수 있어 공격자의 위치를 실시간 역추적 하는데 활용될 수 있다. 본 논문에서는 네트워크의 특정 패킷에 의미적인 워터마크를 삽입하여 워터마크 패킷을 생성하는 워터마크 패킷 생성 시스템을 설계하고 구현한다. 이 시스템은 중간 경유지를 활용하여 우회 공격하는 공격자의 실제 위치를 실시간 역추적 하는 ACT 역추적 기법의 구현에 활용되었다.

China is defending the terrorist crime through the Anti-Terror Law and anti-terrorism criminal legislation. China's Anti-Terror Law and the Criminal Code Amendment (9), which were promulgated in 2015, provide legal grounds for preventing and hurting ever-growing terrorist crimes. In particular, China's amendment to the Criminal Code (9) is designed to rigorously enforce the legal framework for terrorist crimes, protect prejudicial rights that might be violated by serious terrorist crimes, and protect the penalties for terrorist crimes. However, China's anti-terrorism legislation still has drawbacks such as lack of systematicity, limited regulatory boundaries, and lack of rigorous penalties for the establishment of anti-terrorism legislation. To counter this, China's anti-terrorism legislation must strictly regulate the legal system of terrorist crimes, secure penalties, and prescribe anti-terrorism laws as professional chapters.

By comparing and analyzing the September 11 terror attack news reports on the daily papers in the U.S., Korea, and China, this research found that national ideology and international relationship concerned have affected news report frames about international dispute matters. Both quantitative and qualitative researches identify differences in news framing. For example, after the September 11 terror attack, the most pages of the USs The New York Times and Korean Chosunilbo were covered with related articles(382 and 192 reports, respectively), whereas Chinese Inminilbo cur down to only 32 reports about the issue. Also in content, both The New York Times and Chosunilbo viewed the September 11 terror attack as evil acts which threatened world peace and justified military action against Afghanistan as inevitable revenge and justice for such evil acts, in the point of the USs official view. However, Inminilbo gave out news only based on facts in a neutral viewpoint. Moreover, regarding American military intervention, the Chinese newspapers held very different news frame from the other two by describing considerable sacrifice and pain of innocent people of Afghanistan seriously. For the story composition, daily newspapers in all three countries took the same way to report focusing on specific events with episodes.

Considering that interkorean relations got worse and worse recently, cyber terror of North Korea has seriously become a possibility. Therefore, DoS(Denial of Service), a typical way of cyber terror, is becoming a big issue. Consequently, people are growing more and more interested in information security. Internal DoS attacks, out of a variety of ways of Dos attacks, include disks and memories and shortages of process resources. PAM(Pluggable Authentication Module) is one of the ways of preventing internal DoS attacks in Linux system. This paper provides with a method to internally respond to dos attacks and efficiently prevent shortages of resources by utilizing PAM.

Ie is popular belief among the authorities concerned and their apologists that media coverage of terrorism promotes terrorism and is used as publicity by terrorists. Generally speaking, however, in reporting terrorism, the media become not terrorists' but state's means of publicity, and condemn terrorism, while rationalizing state's violence against terrorism. Terrorists may be successful in attracting public attention at the initial stage of terrorism, but usually fail in publicizing their cause. This fact notwithstanding, the authorities concerned and their apologists maintain thar media coverage of terrorism should be controlled, because it works as publicity for terrorists. Now it can be said that there is an intention to control the media when it is asserted that media coverage of terrorism works as publicity for terrorists. To present these arguments, this article discusses the news values and publicity aspect of terrorism, reviews some problems of and misunderstanding about media coverage of terrorism, and for illustrations, look into the American media's coverage of the 9-11 terrorism against the U. S. and "war on terror". that is, state terrorism taken as a countermeasure to it by the U. S.

While evolving information-oriented society provides a lot of benefits to the human life, new types of threats have been increasing. Particularly, cyber terrorism, happen on the network that is composed of a computer system and information communication network, and the mean and scale of damage has reached a serious level. In other words, it is hard to locate cyber terror since it occurs in the virtual space, not in the real world, so identifying "Who is attacking?" (Non-visibility, non-formulas), or "Where the attack takes place?" (trans-nation) are hard. Hackers, individuals or even a small group of people, who carried out the cyber terror are posing new threats that could intimidate national security and the pace and magnitude of threats keep evolving. Scale and capability of North Korea's cyber terrorism are assessed as world-class level. Recently, North Korea is focusing on strengthen their cyber terrorism force. So improving a response system for cyber terror is a key necessity as North Korea's has emerged as a direct threat to South Korean security. Therefore, Korea has to redeem both legal and institutional systems immediately to perform as a unified control tower for preemptive response to cyber terrors arise from North Korea and neighboring countries.
